The baron of Hell is an enemy monster which resembles a minotaur, faun or satyr with a pink torso, brown goat legs, and a skeletal face.

A pair of barons, referred to internally by id Software as the “bruiser brothers,” star as the bosses at the end of Knee-Deep in the Dead, the first episode of Doom. Barons also appear as regular enemies in the later episodes and in the sequels; coincidentally, they and their weaker counterparts the Hell knights frequently appear in pairs.

They are described in the Doom instruction manual as such: “Tough as a dump truck and nearly as big, these Goliaths are the worst things on two legs since Tyrannosaurus rex.” The Doom II manual later described them as follows: “The Hell Knight was bad news but this is Big Daddy. These bruisers are a lot like Hell Knights, but look a little different and are twice as tough to kill.” The original baron description was given to the Hell knight in Doom II’s instruction manual.
